Recent Developments in the Design and Construction of CRCP Towards a More Durable Concept

Conf-paper-iscr

The technique of continuously reinforced concrete for pavement construction is being applied in Belgium since the 1960s. The original design underwent several changes over time, sometimes for economic reasons but mostly in order to improve the long term behaviour of the pavements. Today there are still possibilities for further optimisation,...

Comparison of Two Rehabilitation Worksites of Motorways Single Versus Double Layered CRCP

Conf-paper-iscr

The technique of continuously reinforced concrete is used in Belgium for the construction or rehabilitation of heavily trafficked motorway sections. Since a few years, double layered CRCP is being considered in order to improve the rolling noise characteristics of the surface. In this paper, two worksites where CRCP was used,...

Experimental Short Continuously Reinforced Concrete Pavement Crack Pattern and Load Transfer Efficiency Across Cracks

Conf-paper-iscr

As a proposed long-term pavement solution for bus stops and corridors in highly urbanized areas, four experimental short continuously reinforced concrete pavement (CRCP) sections with different percentages of longitudinal steel were built in São Paulo, Brazil. The pavement sections are only 50 meters long each, a short constructive length in...

Advancing the Use of Continuously Reinforced Concrete Pavement in the USA

Conf-paper-iscr

The use of continuously reinforced concrete pavement (CRCP) is enjoying a renaissance in the United States (USA). CRCP has the potential to provide a long-term, “zero-maintenance,” service life under heavy traffic loadings and challenging environmental conditions, provided proper design and quality construction practices are utilized. In the USA, the Federal...

Movement of Unanchored Terminus of Continuously Reinforced Concrete Pavement

Conf-paper-iscr

The longitudinal displacements of the terminus of the continuously reinforced concrete pavement (CRCP) without the terminal anchor lug system were measured and analyzed to investigate the maximum terminal joint width and the necessity of the anchor lug system. The terminal movements under environmental loads were measured at the CRCP sections...

Continuously Reinforced Concrete Pavement with Asphalt Top Layer or Surface Texture from Diamond Grinding- the Trial Site on Motorway A94

Conf-paper-iscr

For many years, the traffic volumes and percentage of heavy traffic on German roads and motorways have steadily increased and this trend is expected to continue in the future. To guarantee mobility in the future, road construction with a maximum service life and a minimum of necessary maintenance are needed....

Restrained Shrinkage Cracking of Continuously Reinforced Self-Consolidating Concrete Roads

Conf-paper-iscr

Continuously Reinforced Concrete Pavements (CRCP) are designed in such a way that the longitudinal reinforcement limits the widths of the transverse cracks in the pavement in order to prevent the water, chemicals and deicing salts from penetrating into the pavement. Self-Consolidating Concrete (SCC) is a new and innovative concrete type,...

Skid Resistance Properties of Concrete Pavement Surfaces in Tunnels

Conf-paper-iscr

Skid resistance properties of concrete pavement surfaces in tunnels are measured with the dynamic measuring device TRT on a regular basis in the Czech Republic. Measurements are usually carried out before and after putting the tunnel into operation and then approximately once a year; the skid resistance is also measured...

Walloon Design Method for Concrete Pavements Improvements Since 2003

Conf-paper-iscr

The Administration of the Ministry of Equipment and Transport of the Walloon Government, together with researchers of the Federation of the Belgian Cement Industry and the Belgian Road Research Centre, put into practice a software program for the structural design of pavements. This program is in use for several years...

Air Purification and Self-Cleaning Materials Photocatalytic Pavement Blocks on the Leien of Antwerp

Conf-paper-iscr

Heterogeneous photocatalysis is a rapidly developing field in environmental engineering. It has a great potential to cope with the increasing pollution by traffic. The addition of a photocatalyst to ordinary building materials such as concrete, creates environmental friendly materials by which air pollution or pollution of the surface itself can...

Continuously Reinforced Concrete Inlay at Townhill Compulsory Truck Stop

Conf-paper-iscr

The aim of this paper is to present an overview of the construction of a continuously reinforced concrete inlay at the compulsory truck stop on an interstate freeway: National Route 3, Section 3, km 20.0. The truck stop is situated in a truck lane on the southbound carriageway of the...

Long Life CRCP

Conf-paper-iscr

Continuously reinforced concrete pavement (CRCP) has been constructed on major highways in several countries since the 1940’s. A large majority of these pavements have carried very heavy truck traffic but required low maintenance. Some have experienced problems due to inadequate design, support, and construction. This paper focuses on factors that...
